Long-term longitudinal follow-up of individuals with UCLP after Gothenburg twostage palate closure: surgical and speech outcomes.

Background: Delayed hard palate closure in unilateral cleft lip and palate (UCLP) patients show on a safe surgical method and good speech outcome, however, occurrence of orally retracted articulation before hard palate closure at 8 years. The aim of this study was to describe surgical and speech outcome in UCLP patients closing the hard palate at 3 years.

Methods: A consecutive of 28 participants were operated with Gothenburg two-stage method including soft palate closure at 6 months and hard palate at 3 years. Surgical and speech outcome were evaluated. Recordings of sentences and spontaneous speech at 5, 10, 16, and 19 years were analyzed blindly and independently by three speech-language pathologists. Compensatory articulation, hypernasality, hyponasality, weak pressure consonants, and nasal air leakage were evaluated on ordinal four-point and intelligibility and perceived velopharyngeal function on three-point scales.

Results: Long-term follow-up revealed a safe surgical method. Articulation disorders were present in 25-30% at 5-year but largely not later. About 20% had incompetent velopharyngeal function at 5 years but none at 19 years. Most participants were well intelligible after 5 years. Hard palate closure at 3 years indicated less occurrence of orally retracted articulation compared with a cohort who had hard palate closure at 8.2 years.

Conclusions: Long-term, follow-up of individuals with UCLP after Gothenburg two-stage palate closure including closure of the soft palate closure at 6 months and hard palate at 3 years of age shows a safe surgical method and indicates less retracted oral articulation compared with hard palate closure at 8 years.
